Two Worlds in of itself actually doesn't have THAT unique of a plot. We've seen the son of a gangster trope countless times. Not to mention the world/time traversing trope isn't becoming that uncommon. Like with Memory in the Letter or Time the series. (Which is awful, do not watch Time.) However what does make Two Worlds stand out from the rest is the fact that with time, interaction, and explanation, the other side characters begin to gain their memories from the other world as well. Which I feel was it's strongest aspect. As it involves the side characters more, since they also have personal feelings attached to Khram despite not interacting with him in the second world and even in some cases, are dead themselves in the first.

That being said, despite this extremely well done twist with this trope, the rest of the series is kind of meh in my opinion. While I did enjoy the more intimate scenes, I feel like they were a little played out and randomly inserted as filler space for any given episode at a time. Once again, the all too well worn out trope of the gangster's son didn't really bring out anything new to the table or was all that interesting. Sure it brought about drama but the anti-climatic ending of Thai's father only executing himself wasn't very satisfying. And as soon as that happens it feels like that entire plotline of Thai being the new boss of the gang is just kind of dropped.

Another really big gripe with me was the first world's Thai Who gets bitten by a snake and dies... Just before the second world's Thai arrives. Don't get me wrong I'm glad it ended up that way but it was so out of left field that it was pretty hard to take it as anything but a last minute cop-out of "Oh well there can't be two of these mfs walking around."

Overall though this is definitely worth a watch, was able to go through all ten episodes in a single day and enjoyed myself enough to do that. I would suggest this BL to someone who likes plenty of spicy scenes and doesn't mind some questionable logic of characters or happening coincidences to move the plot along.
